Stupid Newbie Question # 2433 Double Track & Radius

Kato makes it very easy to do what you want to do. They offer curves with various radii to make 33 millimeter track centers. These are 381,348,315, 282, 249 and 216. These will make concentric curves with 33 millimeter track centers. I have double track and have used mostly 282 and 315 millimeter radius curves and they work fine even with locomotives with 3 axles trucks and with Beth Gon coal porters. You have to change the drawbar on the locomotive to pull Beth Gon coal porters because they uncoulple on the curves otherwise. <br /> <br />I want to add a third track and had considered using 249 millimeter radius curves on the inside of the 282 millimeter radius curves but have decided that may not good. I will change my layout and instead use 348 millimeter radius curves on the outside of the 315 millimeter radius curves. <br /> <br />The Kato brochure shows two No. 4 turnouts to make a crossover between two tracks with 33 millimeter track centers. I tried that and they are not satisfactory with many derailments. I gave up on those crossovers and instead got the Kato double crossover. That works good with rarely a derailment. I am unhapppy with the No. 4 turnouts anywhere. Their No. 6 turnouts work good but you cannot make crossovers with 33 millimeter track centers with them. I used No. 6 turnouts for my first yard track which makes 49.5 millimeter track centers. I then used No. 4 turnouts in the yard to get 33 millimeter track centers but I have a lot of problems with the No. 4 turnouts.
